Supply & Fixing of MS Iron railing of approved design of 12 mm square bar and 16 mm Sq bar and square box of 50x50 mm & M.S. Channel 75x37.5x4 mm including cost of all material, labour, T&P etc. required for proper complition of work as per direction of E/I

Supply and fixing of reflective raised pavement marker with its body surface made of tough ASA (Acrylic styrene Acrylonitrite) or HIPS (Hi- impact Polystyrene) or acrylonitrile butadiens styrenc (ABS). The marker shall supported a load of 1335 kg tested in accordance with ASTMD 4280 and its reflective panels shall consist of number of lenses containing single or dual prismatic cubes of providing total internal reflection of the light entering the lens face. Retro reflecting surface shall preferably be 35± 50 to base and area of each retro- reflecting surface shall not be less than 13.0 sqcm road studs shall be legibly marked with name trade mark or other means of idenfification of the manufacturer. Dimensions of road studs should not be less than 100 mm x100mm x10mm Without Shank

The solar cateye shall be produced from an engineered polymer selected for superior impact resistance and weather-ability. The top of the marker should be transparent for solar charging and light output in active mode. The base of the body shall be yellow or neutral white as approved by Engineer In-charge. The marker shall incorporate a solar panel (comprising of solar cells) for converting solar energy into electricity, a storage device for storing the energy, LEDs for illumination and a design for providing 360 degree uniform smooth illumination through light tube. The marker shall also have high reflective plastic lenses for conspicuity in passive mode and dual shanks for improved road presence. These markers are intended for application directly onto pavement surfaces and shall be applied with epoxy resin adhesives designed for use with raised pavement markers and as supplied by the marker manufacturer separately. The solar cateye shall be of height: 65 ± 2 mm & Maximum Diameter: 136 ± 4 mm. The solar stud/ cateye shall be tested for water ingress as per IP 65 standards & IP 68 standard & compressive strength of 13635 Kg tested in accordance with ASTM D4280 and test report shall be submitted at the time of bidding of tender. If somehow tender pre qualification condition do not ask for government report then the report shall be submitted to engineer-in-charge before finalization of bill. The rate shall include all materials, labour, equipments, fabrication, transportation, erection, installation and incidentals all complete as per direction of the Engineer-in-Charge.

Providing and Fixing of Flexible Median Markers as per IRC 79-2019 which shall be made of combination of tough, high impact resistant molded thermoplastic body along with florescent yellow color retro-reflective type XI sheeting with minimum exposed reflective area 285 square mm and with rebound property. The reflective sheeting should confirm to Type XI Florescent Yellow sheeting as per IRC 67 2012 and ASTM D4956-11. The flexible median marker shall have overall height of minimum 180 mm, body thickness of minimum 2mm and shank depth of minimum 30mm. The retro-reflective sheeting shall be on both sides of the Flexible Median Marker and shall be edge protected with no exposed edges which will prevent edge lifting, vandalism, sheeting damage, etc. The edge of sheeting should not come out easily by putting nails, sharp objects etc. The logo of the manufacturer shall be embossed on either side of the body. The product design has to with stand all natural impacts and should not get damaged if any pedestrian stamp on top of it intentionally or unintentionally. The product should bend up to 90 degree on both sides without breakage or damage. The product shall be tested for reboundability & tensile test as per IRC 79-2019 and government lab test report shall be submitted along with tender. If somehow tender pre qualification condition do not ask for government report then the report shall be submitted to engineer-in-charge before finalization of bill. The rate shall include all materials, labour, equipments, fabrication, transportation, erection, installation and incidentals all complete as per direction of the Engineer-in-Charge.
